I'm not actually sure myself, but I was really surprised to learn how profitable it is. SpaceX made $15b of revenue last year and $8b of profit. Starlink was 60-80% of that!

It turns out the demand for really good internet everywhere is huge.

Absolutely false.

The article claiming "$8b profit" is relabeling EBITDA. EBITDA only tells you that Starlink makes money on a satellite once it is already in space and connected to a user. It deletes the cost of building the satellite, launching the satellite, the user equipment manufacturing, and just about all other substantial expenses.

The fact a Starlink satellite only has a < 5 year lifetime and ~2 burn up in the atmosphere every single day is entirely left out as well.
